Dengue fever, a mosquito-borne illness, has been found to carry a similar risk of Guillain-Barre syndrome (GBS) as influenza and Campylobacter jejuni, according to a recent study published in the New England Journal of Medicine. This finding highlights the potential for dengue to contribute significantly to the neurological burden in regions where it is endemic. The study, conducted by researchers in the UK and Brazil, analyzed national databases to assess the incidence of GBS following dengue infections. The results revealed a striking correlation between dengue and GBS, with a 16.75-fold increased risk of GBS during the first two weeks after dengue symptom onset. This risk remained elevated for up to 42 days post-symptom onset, equating to 35.5 excess GBS cases per million dengue infections. The study's findings underscore the importance of recognizing and treating GBS early in dengue-endemic areas, as the condition can lead to severe neurological symptoms and progressive weakness. This is particularly relevant given the recent large-scale dengue outbreaks in tropical regions, where arboviral infections like dengue may be more prevalent triggers of GBS than Campylobacter jejuni and enteroviruses. The study's authors emphasize the need for clinicians in these regions to be vigilant and consider GBS as a potential complication in patients with progressive weakness during or shortly after dengue infection. Meanwhile, in Burundi, a landlocked country in Africa's Great Lakes Region, an outbreak of a mysterious illness has caused concern. The illness, which has resulted in at least five deaths and 35 illnesses since March 30, has a case-fatality rate of 14%. Symptoms include fever, vomiting, diarrhea, headache, and dark urine, with some cases displaying neurologic symptoms, anemia, jaundice, and difficulty breathing. Despite extensive testing, the samples from patients have tested negative for over 200 pathogens, including Ebola and Marburg virus diseases, Rift Valley fever, yellow fever, and Crimean-Congo hemorrhagic fever. Public health workers are now investigating the possibility of zoonotic transmission, conducting animal testing to determine if the illness has originated from an animal source. The World Health Organization (WHO) is supporting Burundi's health ministry in strengthening disease surveillance and laboratory diagnosis, with the aim of preventing the potential spread of the illness and safeguarding public health.
